Structure and spectral properties for silver nanoparticles preparation by chemical method

Abstract

This search has presented an alternative-novel, easy and fast  method for the preparation of pure and stable noble metal versatile nanoparticles NPs in a high reduce rate and size-selected manner with a high concentration, long period of stability, less aggregation, non toxic and contamination.
Silver nanoparticles were prepared by chemical method from reducing silver nitrate by different three methods. Study the optimum preparation parameters that optimize for the best formation efficiency silver nanoparticles.  UV-Visible spectroscopy can be used as a simple method for monitoring the stability of nanoparticle solutions and can be used other techniques such as transmission electron microscope (TEM), X-ray diffraction  (XRD) and atomic force microscope to detection of silver nanoparticles.
  Aims of the work synthesis of silver nanoparticles and use it as antibacterial agent and synthesis novel nanocomposite as (polymer-Ag NPs).
